Oh, sorry. Yes, I did not state it initially.
One more question, the .* makes it match anything. But can I match only valid declarations? That is, the variables should start with alpha, can have only alphabets and numbers. Let's assume lowercase only. How do you tweak the above to check for that?
Hi, no the .* will not match anything, since they are embedded in context. What is your additional question? I think you question about back references is answered. If so, it may be better to start a new topic.

zgrep
ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci-
fied, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and
fed to grep.
If zgrep is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, zgrep uses
it as the grep program to be invoked. For example:
for sh: GREP=fgrep zgrep string files
for csh: (setenv GREP fgrep; zgrep string files)
